Dissomphalus plaumanni Evans, 1964

Dissomphalus plaumanni Evans, 1964: 47 , 52, 58–59 (♂, holotype from Santa Catarina, BMNH, figs 19, 27, 32, 35); Azevedo, 1999b: 939 –941; 2003: 26–27; Redighieri & Azevedo, 2004: 330; 2006: 312; Colombo & Azevedo, 2016: 33 –34.

Diagnosis. Mandible tetradentate. Clypeus trapezoidal. Tergal process lateral with shallow depressions, pair of turbecles with pit of setae on top. Hypopygium with posterior margin convex with small conical expansion. Genitalia: paramere with acute apex and arched inward, dorsal margin developed; aedeagal ventral ramus short than aedeagal dorsal body, as high as base of cuspis; wide; laminar; inner and outer margins straight and slightly convergent; apex acute with outer margin slightly concave with ventral surface slightly directed outward; aedeagal dorsal body with pair of apical lobes, laminar, wide with rounded apex in lateral view, compressed in dorsal view, below the apex. Apodeme extending beyond genital ring.

Remarks. This is one of the most widespread species through the Neotropical region ( Azevedo 1999b) and here more specimens are added. Some variations are worth to mention: median clypeal tooth angulate; median carina clypeal straight and complete; vertex crest straight; tergal process with very small and very shallow depression; pit of tubercle with few setae.
